Abstract: A light control film includes opposing substantially planar substantially parallel first and second major surfaces spaced apart along a thickness direction of the light control film by less than about 500 microns; and a plurality of substantially parallel optically transparent polymeric columns disposed in, and substantially surrounded by, a light absorbing polymeric material. Each of the polymeric columns has a first column end at the first major surface and an opposite second column end at the second major surface and has an aspect ratio of greater than about 3, such that the first column ends of at least one pair of adjacent polymeric columns include substantially parallel substantially straight sides facing, and substantially coextensive with, each other.

Abstract: A thermal interface layer includes pluralities of first and second particles dispersed in a polymeric binder at a total loading V in a range of about 40 volume percent to about 70 volume percent. The first and second particles have different compositions. The first particles include one or more of iron or nickel. The second particles include one or more of aluminum, magnesium, silicon, copper, or zinc. The thermal interface layer has a thermal conductivity in a thickness direction of the thermal interface layer in units of W/mK of at least K=5.1−0.17 V+0.002 V2.

Abstract: Optical films for redirecting light are described, and optical systems, such as display systems, incorporating such optical films are described. The optical film may include a first structured surface including a plurality of prismatic structures, and a second structured surface opposing the first structured surface and including a plurality of microstructures. An effective transmission of the optical film is not more than 1% less than a film with a comparable construction except for a smooth, non-structured second surface.

Abstract: The disclosure generally relates to efficient hollow light duct bends (200) that are capable of retaining a higher on axis transmission for partially collimated light propagating within a light duct (220, 230). In particular, the described hollow light duct bends (200) include input and output plates (214, 216) that have low reflectivity for near nonnal incident light, and high reflectivity for near grazing incident light.
